The ATP has already held meetings with the WTA to discuss sharing ideas and pooling resources on particular marketing efforts and infrastructure.

Additionally, the ATP is interested in some form of the WTA's mentor program, which pairs a player 18 or younger with a recently retired player. Larry Scott, the ATP's chief operating officer, said the ATP and WTA plan to conduct a joint educational program for junior players at Wimbledon.

The public's appetite for combined events is strong, the report found. There are 16 combined events, it said, and plans are in the works to add another one in Europe. Down the road, Scott said, a combined season-ending championship is "realistic" for the ATP and WTA.
